comparing two offers where one pays more and one has a much clearer growth path and I don't know how to weigh those against each other

Offer A: better pay now, flat structure, no defined senior track visible from outside. Offer B: lower pay, but the team lead walked me through what the next two promotion cycles typically look like in real detail during the interview itself. Money is money but I keep coming back to how much more specific B's answer was when I asked about growth.
